can't wire my yamaha - help needed

[redxpuser]

Hi everyone,
I have recently purchased a yamaha 28 outboard with electric start and electric choke.
I don't think it had been used on the electric start by the previous owner, as it has pull start as well.

The problem I have is this :
The engine has 3 wires coming out under the hood - a red, a black and a white. (also have battery cables fitted already.
If I touch the red and black together, the motor will turn and fire. There is no stop switch, so I don't know how to stop it.
I have a stop switch on a lanyard (2 wire) but don't know where to connect it.
Can I just fit a push button start switch to start it by connecting to the red and black wires ?
The white wire is supposed to be the engine stop circuit, but don't know where to wire it to.

ANY HELP greatly appreciated, as I am nearly at my wit's end.

Thanks, Andy

Andy,

Shorting the white wire to ground (black) should stop the engine - so you want to wire the kill switch to do this when the lanyard is removed.

I'd have expected the starter to be on a brown wire?

There are some wiring diags here:

Assuming the red and black wires go to the starter solenoid then yes.

Connect it to the kill lanyard switch and connect the other side of the lanyard kill to the engine casing or earth.


If you're still having problems and need it wiring up drop me a PM-I'm only 30 mins up the road here.
